l. D. PERRY noon BUMPER AND THE LIKE Filed Sept 22. 1931 Patented Oct. 25, 1932 UNITED STATES PATENT OFFICE IRA D. PERRY, OF CHICAGO, ILLINOIS, ASSIGNOR TO EDNA L. MEYER, OF ROCKFORD, ILLINOIS DOOR BUMPER AND THE LIKE Application filed September 22, 1931. Serial No. 564,269.

This invention has to do with improvements in door bumpers and the like. The door bumpers herein disclosed are especially intended for use in connection with the doors of automobile bodies and similar locations.

In the construction of automobile bodies, it is customary to provide a door frame construction which is provided with a ledge facing in the direction of door closing movement; and the door frame is also usually provided with an inwardly extending flange lying parallel to the direction of door closing movement. The edge portion of the door itself is provided with a companion ledge which faces in the direction of door closing movement and approaches towards the ledge of the door frame as thedoor is closed. The edge portion of the door is also provided with a surfacewhich lies parallel to the direction of door closing movement and moves past or opposite to the inwardly extending flange portion of the door frame. In some cases, also, the door frame is provided with an outwardly extending flange lying parallel to the direction of door closing movement'and located along the other edge of the ledge of the door frame.

It is also customary in many cases where the automobile body is provided with two doors on each side, to locate a stanchion or door pillar in the door frame and between the adjacent edge portions of the two doors, which stanchion or door pillar establishes the companion portions of the frame openings for the two doors.

The door bumpers are located on or adjacent to the ledges of the door frames or stanchions or pillars, and are contacted by the companion ledge portions of the doors as the latter are closed.

In certain previous constructions, it has been customary to provide a socket or recess in the ledge portion of the door stanchion or frame into which socket or recess the bumper block is placed and secured. In such previously known constructions, it has also been the custom to locate a clip or retaining memher which is so formed as to secure and retain the bumper block in place. This has been objectionable because it has entailed the use of additional parts which must be secured in place, and has thereby increased the manufacturing costs as well as increasing the lia bility of the parts to become loosened ordis' connected under impact in service.

The main objection of the present invention is to provide a sheet metal stanchion or door pillar or frame construction which is so formed as to provide the ledge facing in the direction of door closing movement, together with the inwardly extending flange lying par allel to the direction of door closing move ment, and if desired, the outwardly extending flange also lying parallel to the direction of door closing movement; and to also so arrange and form the parts that there is provided an integrally formed socket or recess reaching inwardly from the ledge and backwardly from the inwardly extending flange, so as to receive the door bumper and provide a seat for the same, said sheet metal also being so treated as to provide integrally formed lugs or parts which receive and co operate with companion parts of the door bumper block in order to retain the same in place. These lugs or parts are so formed that they permit the bumper block to be placed into place into the socket or recess and retained therein, the arrangement being such that the bumper block is set into place in the direction of door closing movement and is retained against withdrawal from the socket or recess at right angles to said direction as well as backwardly in said direction.

Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

- In each of the constructions herein disclosed, the door pillar includes the ledge 20, which faces in the direction of door closing movement, together with the inwardly extending flange 21, which lies parallel to the direction of door closing movement. In each of the constructions herein illustrated, there is also provided an outwardly extending flange 22, lying parallel to the direction of door closing movement. In each construction also, the sheet metal of the door pillar is so treated as to provide a bumper block socket having a floor which faces generally in the direction of door closing movement, and also a back wall lying generally parallel to the direction of door closing movement. In each case, also, the sheet metal of the door pillar is so treated as to provide integrally formed lugs or projections which are adapted to engage the bumper block in order to retain the same in place. i

In the construction of Figures 1, 2, 3, and 4, the sheet metal of the door pillar is so formed as to provide the floor 23 the back wall 24 of the socket; the back wall being in effect a continuation of the outwardly extending flange 22 and the floor 23 being formed from a portion of the metal of the flange 21. It will be noted also, that in the arrangement of the Figures 1, 2, 3, and 4, the socket floor 23 slopes downwardly at a slight angle and the back wall 24 is deflect" ed forwardly at a slight angle so that when pressure is exerted on the bumper block in the direction of door closing movement, there is atendency for the bumper block to work backwardly and downwardly into the rear corner of the socket. It will also be observed that the treatment of the sheet metal of the door pillar is such as to provide endwise facing openings 25 and 26, at the position of the socket or recess. Furthermore, it will be noted that the sheet metal of the door pillar at the position of the ledge 20 is so treated that the edges of the socket or recess slant backwardly and away from each other, thereby in effect providing a dove-tail shaped opening which eflect is most apparent from examination of Figures 3 and 4. These are the edges 27 and 28. It will also be noted that the sheet metal of the ledge 20 is so treated as to provide the downwardly GX= tending lugs 29 at the edges 27 and 28, which lugs give additional strength to said edges and also serve as portions which will engage the companion portions of the bumper block when set into place.

The bumper block is designated in its entirety by the numeral 30. It is of rubber or other suitable resilient material. It includes a body portion which is suitably 1 formed so that it can be slipped down into the socket or recess and will then rest upon the floor 23 and against the back wall 24. Said bumper block is also of a size so that it extends somewhat above the ledge 20 and thus establishes a pressure and impact receiving surface against which the ledge portionofthe door contacts during the door closing movement. I

The bumper block also has its body portion of wedge or tapered form so that it can be slipped down into the socket or recess in the direction of door closing movement, but cannot be pulled therefrom at right angles to such direction. evident from examination of Figure 3.

The bumper block is also provided with the endwise projecting lugs 31 and 32 which can be forced under the edge portions of the ledge 20 at the positions of the lugs 29 so as to lock the bumper block in place and retain it against accidental removal in the direction of door closing movement.

If desired, the body portion of the bumper block may also be provided with a down.- wardly extending lip 33 which slightly overlaps the edge portion of the flange 21 at the position of the socket or recess and with other lips 34 and 35 which slightly overlap the side Such fact is principally edges of the flange 21 at the position of the socket or recess.

In the construction of Figures 5 and 6, the sheet metal is so treated as to provide an outwardly extending lug 36 at the position of the floor 23 and the inwardly reaching lugs 37 and 38 in the upper portion of the socket or recess. Said lugs 36, 27, and 38, serve conjointly to retain the bumper block 39 in place within the socket against removal at right angles to the direction of door closing movement. Said bumper block may also be provided with endwise projecting lugs 40 corresponding to the lugs 31 and 32 previously explained.

In the construction of Figures 7, 8, and 9, the sheet metal of the back wall 24: of the socket is so treated as to provide a pair of forwardly extending lugs 41 and 42 which approach each other on an angle so that they dove-tail towards each other. The bumper block 13 is in such case provided with a backward projection to engage said lugs 41 and 42 and engage the same in such manner that the bumper block cannot be pulled away from the socket or recess in a direction at right angles to the direction of door closing movement.

p In the modified construction of Figures 10 and 11, the sheet metal of the flange 21 is so treated as to provide the inwardly slanting lugs 44 and 45, at the sides of the socket, and the bumper block 46 is provided with companion slots or recesses which receive and engage said lugs. In this case, the bumper block is retained against withdrawal from the socket or recess at right angles to the direction of door closing movement, but can be set into place by a movement in the direction parallel to the direction of door closing movement.

In the construction of Figures 12, 13 and 14, the flange 21 is so treated as to provide the lugs 47 and 48 at the sides of the socket or recess, which, however, only reach inwardly a slight distance. In this case, the bumper block 49 can be forced down into the socket or recess by movement in a direction parallel to the door closing movement, the material of the bumper block compressing slightly in order to permit this to be done. Such result is evident from examination of Figure 14 in particular. hen the bumper block is thus forced into place, its edge portions 50 and 51 will bulge slightly so as to give a finished appearance at the side edges of the socket.

In the modified construction of Figure 15, the sheet metal of the door pillar is so treated as to provide lugs 52 and 53 at the sides of the socket or recess somewhat similar to the lugs 47 and 48, of Figure 13; but these lugs 52 and 53 are tapered slightly as shown in Figure 15.

It will be noted that in each case, the sheet metal of the door pillar is so treated as to provide the lugs or similar parts which are integral therewith and constitute in eflect clip members or elements which will retain the bumper block in place without the necessity of providing and using other clip members as in previously known constructions.

I claim:

1. A door buffer device comprising a metal door pillar member cut and bent to provide substantially parallel flanges spaced by integral impact ledge and bumper seat portions, said portions extending in parallel spaced planes connected by a bumper backing portion, said backing portion forming with said seat an angular continuation of each of said flanges, a resilient bumper block engaging said seat and backing portions, and a lug element projecting from a cut edge of said member and cooperating with said seatand backing portions to retain said bumper block in position adjacent said impact ledge.

2. A door buffer device comprising a metal door pillar member cut and bent to provide substantially parallel flanges spaced by in tegral impact ledge and bumper seat portions, said portions extending in parallel spaced planes connected by a bumper backing portion, said backing portion forming with said seat a recessed continuation of said flanges, lug elements projecting from edges of said out and bent portions into said recess, and a resilient bumper block adapted to rest upon said seat and backing portions and having means engaged by said lug elements.
